SPECIFICATION forming part of Letters Patent No. 405,105, dated J' une 11, 1889.

Application filed December 10, 1888. Serial No. 293,149. (No model.)

.To all whom t may concern:

Be it known that I, JACOB LoEwENrHAL, a citizen of the United States, residing at Chicago,` county of Cook, and State of Illinois, have invented certain new and useful Improvements in a Lock-Register,which are set forth iu the following specification.

This invention relates to registering mechanism, and is especially designed to be applied to locks or looked receptacles to register the number of times the 1.ook or receptacle is opened.

In the drawings, Figure 1 is a front elevation of a padlock containing my register. Fig. 2 is a plan of the registering mechanism, the adjacent portions of the lock-case being shown in section, as at the line 2 2 on Fig. 1. Fig. 3 is an axial section through the registering mechanism. Fig. 4: is an enlarged detail representation of the first registering-wheel and its immediate actuating mechanism, the parts being shown in the position which they occupy when the lock is closed. Fig. 5 is a similar view showing the same parts in position just after the opening of the hasp has been begun. Fig. G is a section at the line 6 6 on Fig. 4.. Fig. 7 is a side elevation of the shaft upon which the registering-wheels are mounted. Fig. S is a plan of two adjacent registering-wheels and an intermediate pinion which communicates motion from one to the other, showing the locking device. Fig. 9 is a detail of the locking device in a different position from that showuin Fig. 8. Fig. 10 is a plan of a blank from which the lockingcam is formed. Fig. 11 is an elevation of a disk by means of which motion is primarily communicated to the register-train from the hasp, the actuating projection of the hasp being shown in section, the position lbeing as when the lock is opened. Fig. 12 is asimilar view, the relative position of the projection and disk being that which they occupy when the lock is closed. Fig. 13 is a detail perspective of the hub of the hasp, showing the register-actuating projection. Fig. 14. is a section through a drawer-head in which a slightly-modified Iform of the device is inserted, showing the registering device in end elevation, a portion of the case being broken away to show so much of the mechanism as is different from th at illustrated in the former figures. Fig. 15 is a section through the registering mechanism at the line 15 15 on Fig. 14. Fig. 16 is a section through the padlockcase at the line 16 16 on Fig. 1.

I will iirst describe this mechanism as it is applied to a padlock.

A represents the padlock-case; B, the hasp, which is pivoted to it in the usual manner and position at h. The side walls of the case A are protruded somewhat farther than would be necessary for the ordinary purpose of the padlock, and they may be deected inward so that they meet, and with the end wall A and the top wall make a complete inclosing-case for the registering mechanism. For convenience, this inclosing-case, as a whole, may be hereinafter referred to by the name registercase.

The registering mechanism comprises the parts which are grouped about the shaft C. This shaft is designed to be inserted into the register-case from one end, and when applied to the padlock, as illustrated, it is inserted from the end at which the hasp is pivotcd, so that when the hasp is inserted its hub B closes the case. The shaft C terminates at the farther end in areduced bearing C,which is lodged in a suitable socket in the end wall A of the case, and is made fast therein by the pin c', inserted through said end wall and shaft. The shaft is further secured by a pin om, inserted through the sidewalls of the case and piercing the shaft at on. (See Figs. 3 and 7.) The shaft is thereby rigidly secured in the register-case. Upon this shaft are mounted the registering-wheels D D and D2,Which are comparatively thin rings constituting crown-gears, which iit upon and rot-ate on the shaft C at the portions Where it retains its full diameter. Said shaft is cut away adjacent to the location of each registering-wheel, as at C2 C2, a segment amounting in thickness to about half the diameter of the cylinder and in length to the diameter of the pinion E', hereinafter described, being removed, and into the remaining portion of the cylinder, at the center of each iiat face c2 thus formed, there is inserted' the stud C20. Upon each of the studs C20 there is journaled apinion E,which mesh, respectively, with the adjacent crown-gears D D2, and in similar relation to the first crown-gear D', but somewhat IOO differently j ourn aled, as hereinafter dese ribed, is the pinion Each of said crown-gears contains the continuous series of teeth (l, and the gears D have at the opposite side from said teeth d a single toothc'tnvhich is adapted to engage and actuate the adjacent pinion E. Rotary motion being communicated to the first pinion lL, which `is journaled and actuated, as hereinafter described, Ait rotates the first crown-gear D', which upon each complete rotation will, by means of its tooth ('Z, rotate the pinion E the distance of one tooth, which in turn, engaging the next crown-gear D, will rotate it one tooth. These crowngears are each provided with ten teeth d, and thus it will result that ten complete rotations of the lirst crown-gear will be `necessary to produce one rotation of the second, and the same ratio will obtain through consecutive gears throughout the series, however many. The periphery oi' each crown-gear bears a scries of figures from O to i), inc-lusi\fe-one cha-racter for each tooth-and opposite the crowngears one side wall of the register-case is apertnred, as at c,to expose the figures successively as the wheels are rotated. The wheels being' set at O-zi. c., with the figures O exposed through all the apertures amthe number indicated by reading the Afigures successively from leftto right will indicate the number of times the first pinion E has been actuated the distance of one cog. This .indication would be corrected only in casenomovement was ever given to any of the registerwheels except through the medium of the train in the manner described, and to prevent any other movement being comnuinieated to them, as might otherwise be done by a tool inserted through the apertures d, l provide the locking mechanism, which l will now describe.

In the bearings of the crown-gears D D DE on the shaft C there are formed the annular grooves C10, and in each of these grooves there is placed the annulus F, formed by vfirst cutting the strip shown in Fig. lO and bending it in the groove Cl until the ends meet, and

said annulus then secured to the crown-gear by means of a pin j" through the hole f. A portion of the bearing of each register-wheel is cut away at C3, and on the flat surface thus formed there is pivoted the dog G, whose thickness is substantially equal to that of the annulus F, the plane at which the bearing Vis thus eut away being tangent to the bottom of the groove (im. The annulus F has the indentation F2, which is conveniently formed by shaping the endsf?, although it might be formed elsewhere in the periphery, and this indentation causes the annulus F to act as acam upon the dog G in the manner which will now be described.

lVhile the crowngear is rotated through nine-tenths of its circuit, the straight portion ot' the edge of the annulus F stops the dog (-r and holds it with its point G protrudin laterally into one of the interstices between the eogs of the adjacent pinion and locks it fast; but at the 'instant that'the tooth d of the crown-gear reaches the pinion and is in contact with it and about to actuate it, the indentation F3 in the annulus F reaches the locality of the dog, as appears in lfig. S, and the dog is therefore free to be pushed hack into the indentation as the pinion engaged by the tooth d rotates and tends to crowd it back. The position when the tooth and pinion are thus engaged is shown `in Fig. f),the dog being shown in dotted lineI ululerneath the crowngear. This indentation extends far enough to permit the tooth d to rotate clear of the pinion, but before it is entirely clear the cam formed by the side of the indentation forces the dog out again, so that the pinion, before it is freefrom the tooth df, is engaged bythe dog and again locked. Thus the pinion is never free to move except at the instant when it is being moved positively by the tooth d', and then Vis only free to move as it is moved by that tooth. This prevents any rotation oi' any of the register-wheels otherwise than as designed through the medium of the pinions, and so causes them each to registerthe number of complete rotations of the next prcceding gear-i. c., to advance one tooth only for each `complete rotation of the preceding gear.

I will now describe the mechanism by wh ich the lirst pinion is actuated.

The forward end of the shaft C is reduced in diameter at the portion C, and upon said reduced portion the cylinder l( is journaled, and the pinion E is journaled upon the stud 7;, which ln'otrudes radially from the outer surface of the cylinder l. The outer dialneter of said cylinder l( is equal to the inner diameter of the crown-gears D, so thatthe pinion E, journaled as described, meshes properly with the crown-gear. The cylinder l( is slotted' circuinferentially at K', Athe angular extent of said slot being something more than thirty-six degrees, t'or a `reason which will hereinafter appear, and a stud L, made fast in the shaft C,1 )rotrudes through said slot and projects beyond the surface of the cylinder l( substantially to the level et' the surface of the crown-gears. This stud L prevents the cylinder l( from rotating on the shaft C more than the angular extent ot' the slot l. At the center ofthe forward end ol' the shaft C the disk ll is journaled on the shoulder of the screw 71 which is screwed `fast linto said shaft. This disk has a linger ll, which folded over longitlulinally"with respect to the shaft upon the outer surface el' the cylinder K. Said linger has a tooth 71.', which is of proper shape, and is in properposition to mesh into the pinion. lll', as seen in Fig. i. lnto the cylinder l( there is rigidly inserted the stud La', which is located at such distance from the pinion lll that when the straight edge of the fingerll rests against it the tooth. 7L .is clear ol. the pinion lC. Upon the protruding end of thestud L there is piv- IOO I'IO

oted the dog M, which has the tooth M adapted to engage with and lock the first register-wheel D', and into the cylinder K, near that which has the tooth M and in so doing to force the dog into engagement with the register-wheel, as seen in Fig. 4. Vhen the dog is thus engaged with the register-wheel, the edge m of the dog M opposite the tooth M stands in the plane of the forward end of the cylinder K. The disk H has beside the fin ger H a projecting portion H2, which extends radially beyond the outer surface of the cylinder K,-

and at such angular distance from the iinger H that when said finger is standing against the stud k said projection H2 stands adjacent to and abutting laterally against the edge m of the dog, so that in that position the said projection H*2 locks the dog to prevent its turning, and to prevent its tooth M becoming disengaged from the register-wheel. Said projection H2, however, laps past and abuts the dog only so far that when the tooth 71, is meshed with the pinion E the projection H2 is clear of the dog.

The operation of this construction is as follows: The parts being shown in the position shown in Fig. 5, the project-ion H2 locks the dog M in its engagement with the registerwheel. The disk H, being rocked on its pivotscrew 7L, first carries the linger H into mesh with the pinion E and simultaneously carries the projection H2 clear of the dog M. The disk H being further rocked, the cylinder K is rotated by reason of the engagement of the finger H vwith the pinion E, which,by reason of the tooth h, cannot rotate on the stud-axle, by which it is secured to the cylinder, and said pinion and cylinder thus rotating, the pinion being in engagement with the registerwheel, rotates it also an angular distance of Aone tooth-that is, until the cylinder K is stopped by the stud L reaching the end of the slot K. This position is shown in Fig. 4. The rotation of the cylinder K would be stopped also by the collision of the stud k2 with the forward end of the dog M, which causes it to rock the dog into engagement with the register-wheel, as also seen in Fig. 4. No further movement of the parts can occur, except upon the reversal of the movement of the disk H. Vhen this occurs, the finger H is first withdrawn from engagement with the pinion E, and simultaneously the projection H2 moves up alongside of the edge m of the dog M and locks it as before. Continuing the reverse movement, the nger H, having now collided with the stud 7c', carries with it in reverse direction the cylinder K, and the pinion E,

mounted thereon, rotates on its stud-aXleby reason of its engagement with the registerwheel, which cannot rotate on account of the dog M locking it to the shaft C, to which said dog is pivoted on the stud L. The reverse movement may therefore continue until the stud L reaches the limit of the slot K in the cylinder, and the parts are then in the initial position shown in Fig. 5.

The rocking movement described alternately in opposite directions is communicated to the disk H by means of the following mechanism. Said disk H has formed in its forward face the cam-recess H3, and from the hub B of the hasp the stud b projects into said recess HS. Then the parts shown in Fig. 5 are in the position therein illustrated, the stud h stands in said recess in the position shown in Fig. l2, and in this position the hasp projects into the lock, as when the lock is' cam-track, rotates the disk until the studv reaches the position shown in Fig. 11, wherein the cam-track stan ds vertical-z'. e., parallel to the plane of movement of the hasp. This amount of movement is calculated to be only sufficient to bring the point of the hasp out of the lock, but not sufficient to leave an interval so that the padlock could be removed from the securing-staple. If the opening movement continues, the stud 1) continues to move upward along the cam-track H30 without further actuating the disk H; but whether further opened or not, when a reverse movement is given it to carry the point down again into the lock, the stud, engaging the cam-track H31, rotates the disk H in a reverse direction until the point of the hasp is carried home into the lock, and the position of the parts is again as shown in Fig. l2. Thus the opening and closing movement of the hasp through so much of its course as is necessary to withdraw the point of the hasp from the lock and reinsert it therein produces the rocking movement of the disk H, which is necessary for the actuation ofthe registering mechanism in the manner described. This registering mechanism may be applied to register the number .of times any receptacle is opened and closed without regard to the presence or absence of a lock in connection with such receptacle, and when thus applied the device for giving the rocking movement to the disk H maybe modified, as shown in Figs. 14 and 15, wherein the device is applied to a drawer, being inserted in the head P of such drawer, and in that instance mounted in an independent cylindrical case A, which is merely a substitute for the register-case formed by the walls of the padlock in the above-described construction. In this modified construction the cam-recess H3 is dispensed. with, and the disk H is connected to the shaft by a spiral spring N, which tendsv IOO IIO

theface of the disk there is pivoted the link N', which protrudes from the register-case and from the drawer-head inward. Any suitable stop as the projection blz-may be provided on the cabinet-front I, so that when the drawer-head is moved sluit the eollision of the protruding end of the link II with said stop causing said link to recede into the register-case causes it to give rotary rocking movement to the disk Il, and when the said part having the receptacle is withdrawn the spring N, reacting, reverses said rotary rocking movement, thus producing the action of the registering mechanism in the same manneras when safd movement of the disk is caused by the rocking movement of the hasp in the instance of the padlock.
